They are a b*std of an axle. I always thought it would be cool to do a dually axle conversion. Until you look at the bolt pattern you would need for wheels, the height, and the width of the wheels. The bolt pattern is a 6 on 8.5 and the wheels are a 14"x6" Basically, you would have to have some wheels custom made. Then there is the spacing of the wheels/tires. In order for the tires to not rub, the frame or each other, you would need two sets of spacers.
